ASoC: SOF: ipc4-mtrace: process pending logs upon FW crash

If the DSP firmware has crashed, some log messages may be pending in the
mtrace buffer, but not consumed by the driver as no IPC notification has
been sent by the firmware. Check the buffer status for all mtrace slots
and ensure any pending log messages are processed before DSP is possibly
powered down and the log buffer contents is lost.
